Just did a search for the latest info on this game. Found a reddit post from 4 months ago that says:

"Yeah, like smushkan said, the Pillow Castle team just graduated recently so it's going through a transitional period. I'm trying to see if I can continue development full-time in a more indie space, but not all of the team are in a good position to take that kind of risk.
Thanks Shardwing. We definitely thought there was a lot of hype about the game and didn't want to disappoint people until we had something really good. That's why we didn't make any giant announcements yet! Games like these can take a long time to make (usually any time from 3 to 5 years), so the last thing we want to do is rush the process and make an incomplete game.
